Overview
Brighten up your interior with the DEF DU6 Z-Wave Solar window, designed for flat roofs and combining convenience, elegant appearance and excellent thermal and acoustic performance. The DU6 glazing unit provides high insulation and safety (toughened outer glass and laminated inner glass). Multi-chamber PVC profiles filled with insulation ensure durability and resistance to weather conditions. The flat finish with an elegant glass segment emphasises modern architecture while the large glazing area increases interior daylight.

Key features

• Heat transfer coefficient Uw = 0.7 W/m²K (selected size 60x60 cm)
• DU6 double-chamber glazing unit (toughened outer glass, laminated inner glass P2A)
• Electric Solar control: solar panel + battery (no external electrical connection required)
• Z-Wave wireless control (remote control / wall switch)
• Integrated rain sensor for automatic closure
• Sash ventilation opening up to 120 mm (12 cm)
• Designed for flat roofs with pitches from 2° to 15°
• Suitable for installation on XRD or XRD/W installation bases (for raised/green/gravel roofs)

Details and components
The DEF DU6 Z-Wave Solar is a flat roof window with a large glazed area to maximise daylight. The glazing unit DU6 reduces heat loss and provides safety thanks to a laminated inner pane (P2A) and toughened outer pane (lifetime hail resistance warranty on outer pane). The actuator operates in Z-Wave technology (actuator model ZWS12 in the standard set), enabling remote control and integration with home automation. The window is powered by an integrated solar panel which charges the battery and ensures autonomous operation even on cloudy days. The integrated rain sensor (ZRD) automatically closes the sash on rain detection.

Appearance and materials

• Window colour: PVC white (RAL 9010) internal profiles
• External cladding colour: Black RAL 9005
• Window material: multi-chamber uPVC profiles filled with insulating material

Usage and accessories
The window can be equipped with internal accessories and external awning blinds to reduce solar heat gain. It is suitable for rooms where natural light and airtightness are important (bathrooms, living spaces, utility rooms). The product is supplied as a set including an electric actuator and rain sensor; the solar-powered variant includes the integrated solar panel and battery for autonomous operation.
